Project No. 23-7-222
Subject: Observation of Excavation, Proposed Steel Building, 796 County Road 259,
Garfield County, Colorado
Dear Gabe:
As requested, a representative of Kumar & Associates, Inc. observed the excavation at the
subject site on November 11, 2025 to evaluate the soils exposed for foundation support. The
findings of our observations and recommendations for the foundation design are presented in this
report. We previously conducted a subsoil study for design of foundations at the site and
presented our findings in a report dated May 8, 2023, Project No. 23-7-222.
The proposed steel building will be supported on 8 footing pads sized for an allowable bearing
pressure of 1,500 psf.
At the time of our visit to the site, the foundation excavation had been cut with 8 pads cut to
between 2 and 4% feet below the adjacent ground surface. The soils exposed in the bottom of
the excavation consisted of medium stiff, sandy silt and clay. No free water was encountered in
the excavation and the soils were slightly moist.
The soil conditions exposed in the excavation are consistent with those previously encountered
on the site and suitable for support of spread footings designed for the recommended allowable
bearing pressure of 1,500 psf. Loose disturbed soils should be removed in the footing areas to
expose the undisturbed natural soils. The bearing soils should be protected from frost and
concrete should not be placed on frozen soils. Other recommendations presented in our previous
report which are applicable should also be observed.
The recommendations submitted in this letter are based on our observation of the soils exposed
within the foundation excavation and the previous (limited) subsurface exploration at the site.
Variations in the subsurface conditions below the excavation could increase the risk of foundation
movement. We should be advised of any variations encountered in the excavation conditions for
possible changes to recommendations contained in this letter. Our services do not include
determining the presence, prevention or possibility of mold or other biological contaminants
(MOBC) developing in the future. If the client is concerned about MOBC, then a professional in
this special field of practice should be consulted.
